If there are options that have been changed in the GUI but have not been
committed to PBSmodelling memory in the global R environment, the user
is prompted to choose whether or not to commit these options.
Then, if any PBS options have been changed, the user is prompted to choose
whether to save these options to the file fname
. (When a new R session is
started or when a call to readPBSoptions
or writePBSoptions
is made,
PBS options are considered to be unchanged; when an option is set,
the options are considered to be changed).
If fname=""
, the user is prompted to save under the file name last used
by a call to readPBSoptions
or writePBSoptions
if available.
Otherwise, the default file name "PBSoptions.txt" is used.
